I wanted to add that I faced the exact same issue with Dell Latitude E7440 (4th generation intel laptop) which is known to have very good compatibility with Linux, I have updated my bios(currently at A07) and the kernel but the problem persisted.
I am using opensuse 13.1 and the kernel from Kernel:stable which is currently 3.13.7-1-desktop and suspend to disk used to work only occassionally, after adding the kernel parameter and restarting it seems to work 100% of the time. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/282220 Title: Hibernate fails on Thinkpad T41 Status in The Linux Kernel: Fix Released Status in “linux” package in Ubuntu: Won't Fix Bug description: I've installed Ubuntu 8.10 (Intrepid) on my Thinkpad T41 (which previously had 8.04 installed) and got all updates available. I can hibernate, and the hard-disk light indicates that memory state is saved to the disk. When I start the machine again, the kernel boots, the Ubuntu splash screen appears (all as in 8.04), and the disk light indicates that memory is initialized again. However, after that, the machine locks up, nothing more happens, except the Caps-lock LED flashing Ctrl-alt-F1-9 did not do anything, i.e. there was no way I could find out what's wrong. I also did not find anything relevant in /var/log/dmesg* or /var/log/syslog* (at least from my view; I'm no kernel hacker). When hibernating, the T41 switches the screen to text/console mode with just a blinking _ cursor. On 8.10, I now get a message about "PCI" and "unable to thaw device" or something like it, which may be relevant to this behavior. (yes, the "thaw..." message appears not on resuming, but on hibernating) kernel is 2.6.27-7-generic #1 SMP Fri Oct 10 03:55:24 UTC 2008 i686 (from uname -a) I'm unsure if this bug is related to bug #134680.
